Chevron Mist Eliminator
Mist eliminators, as the name implies, are designed to remove moisture in industrial processes where liquids and gases come in contact. Several types are available, with different designs suitable for various applications. Chevron mist eliminators, also known as vane-type or baffle-type mist eliminators, are among the most common and offer reliable performance in high liquid load and high capacity processes.
MACH Engineering manufactures chevron mist eliminators capable of removing droplet sizes as small as 10 microns. If you’re interested in learning more about our vane-type mist extractors, call us at (281) 550-3232.
Product Overview
MACH chevron mist eliminators consist of rows of parallel plates, or vanes, arranged in a zigzag formation. As a gas passes through the plates, mist impinges and coalesces on the vane surface, then drains downward, efficiently removing liquid from the stream. Vane-type mist extractors can be used for vertical and horizontal gas flows.
We manufacture our products in horizontal and vertical sections that install in manways of various sizes. Several material choices are available, with options available for use in high temperatures and highly corrosive environments. For more information regarding the appropriate material choice for a given application or to discuss a vane mist eliminator design, contact a MACH Engineering representative directly.
Benefits of Vane Mist Eliminators
Vane mist extractors are essential for reducing product loss due to contamination, improving purity and output capacity, minimizing pollution and protecting equipment from damage over time. Choosing the right mist eliminator is essential to preventing inefficiencies and ensuring productivity across your operation.
Compared to other designs, chevron mist eliminators offer excellent performance at an affordable price point. Their design makes them suitable for use in high-velocity and high-capacity applications, as well as in processes where a wire-mesh type product would clog easily. They offer good turndown characteristics and the lowest pressure drop of any mist eliminator design. Their versatility — and the range of materials and configurations MACH Engineering offers — makes them a smart choice for many applications.
Applications
Potential applications for MACH’s high-performance chevron mist eliminators include:
- Utility flue gas desulfurization (FGD) systems, and other applications requiring high capacity, low-pressure drop mist eliminators with excellent resistance to fouling
- Phosphoric and sulfuric acid plants, or other facilities producing sulfuric acid mist byproduct in drying, intermediate and final absorption towers
- Crude oil refinery vacuum towers, where they are frequently installed in interstage knock-outs to extend compressor life
- Pulp and paper mills, sugar refineries, chemical plants and other facilities, where they are installed in evaporators to ensure steam condensate purity
- Upstream and downstream refineries and gas processing facilities, where they allow for improved throughput while prolonging catalyst life
- Pickling lines, steel mills and foundries
- Any other dirty services or high fouling applications

Frequently Asked Questions About Chevron Mist Eliminators
Learn more about chevron mist eliminators with the commonly asked questions and answers below.
What Is the Best Chevron Mist Eliminator for Industrial Applications?
The best chevron mist eliminator for industrial applications is one matched to your specific gas velocity, liquid load and process chemistry. MACH Engineering’s chevron mist eliminators use a zigzag vane design that supports low pressure drop with strong resistance to fouling. This makes them a dependable choice across demanding environments from FGD scrubbers to oil and gas processing.
How Is a Chevron Mist Eliminator Different From Other Mist Eliminators?
A chevron mist eliminator differs from wire mesh pad designs in its open, parallel-plate geometry. Instead of a dense mesh matrix, chevron vanes use angled zigzag plates that force the gas stream through a series of sharp directional changes. Heavier liquid droplets cannot follow those turns — they impact the vane walls, coalesce and drain by gravity.
This open structure makes chevrons more resistant to fouling and plugging, and capable of handling higher gas velocities and heavier liquid loads than mesh pads. The primary trade-off is that chevron mist eliminators are most effective for droplets of approximately 10 microns or larger, while mesh pads can capture finer mist droplets below that range.
When Should You Choose a Chevron Mist Eliminator?
A chevron mist eliminator is the right fit when your process involves high gas velocities, heavy liquid loads, or environments prone to fouling, such as solids, viscous fluids, or scaling.
Chevron mist eliminators are well suited for the following:
-
Utility FGD systems
-
Crude oil refinery vacuum towers
-
Acid plants
-
Steel mills
These are also best for other dirty industrial services where wire mesh would clog and require constant maintenance. If minimizing pressure drop is a hard constraint for your system, chevrons are often the preferred option over other mist eliminator types.
What Should You Look For in a Chevron Mist Eliminator?
When selecting a chevron mist eliminator, the following are key factors to consider:
-
Droplet size target: Chevrons handle roughly 10 microns and larger.
-
Material compatibility: Stainless steel, polypropylene, PVC and CPVC are common options, depending on temperature and chemical exposure.
-
Flow orientation: Vertical or horizontal installation.
-
Custom sizing: Can the unit be custom-sized to fit your existing vessel or manway?
MACH Engineering designs chevron mist eliminators for a wide range of industrial applications, with configurations available for vertical and horizontal gas flow.
